In the Millikan's oil drop method, which of the following force does not act on the oil drop?

A

Gravitational force

B

Viscous force

C

Magnetic force

D

Electrostatic force

Text Solution

Verified by Experts

The correct Answer is:
C
In the Milikan 's oil drop method, Gravitatinal force equal to viscous force is developed for an applied velocity to the capacitor plates sandwiched with oil droplet . Electrostatic force exist due to changed droplets of oil between thte paralled plates of capacitor.
Hence, Magnetic field does not act on the oil drop.

  • When liquid medicine of density p is to be put in the eye, it is done with the help of dropper. As the bulb on the top of the dropper is pressed, a drop forms at the opening of the dropper. We wish to estimate the size of the drop. We first assume that the drop formed at the opening is spherical because that requires a minimum increase in its surface energy. To determine the size, we calculate the net vertical force due to the surface tension T when the radius of the drop is R. When the force becomes smaller than the weight of the drop, the drop gets detached form the dropper. If the radius of the opening of the dropper is r, the vertical force due to the surface tension on the drop uf radius R (assumning <
